Instead of using a physical key, this app creates an on-screen button that allows you to easily take a screenshot with a single touch.
For your convenience, it provides the following additional features:
1. Cut the top and bottom bars
2. Hide the top bar (date/time, custom text)
3. Insert a watermark to prevent theft
4. Automatic resize
